It's interesting that Bush got the popular vote "mandate" that he was even bothering to hope for. A win in the popular vote by a current margin of over 3.5 million. On the popular vote, you can't even bring up Ralph Nader and his 400,000 votes -- even if you throw all those votes to Kerry, he still loses the popular vote by 3 million. True, the popular vote is not where the election is won or lost, but its a symbolic victory for Bush.
He is now the first President of the United States to win over 50% of the popular vote since his father George Bush Sr in 1988.
